GREASE-CUP.

Specicaton of Letters Patent.

Application filed January 10, 1920. Serial No.1 350,524.

To all whom t may concern.'

Be it known that l, Antenna {l1-instruir JOHN ALLEN, of San Antonio, in the county of Bexar and State of Texas, have invented certain new and useful improvements in Grease-Cups; and l do hereby declare the following to be a full, clear, and exact description of the invention, suoli as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to the lubrication of machine parts, and the object ci the invention is to provide an improved grease cup adapted for this purpose which has a simple andefective means for positively torcing the lubricant through the cup and a complementary tool for actuating the forcing means.

ln the accompanying drawings, Figure l is a view in perspective ot a grease cup and complementary tool embodying my invention. F ig. 2 is an elevation with the grease cup and part of lthe tool shown in longitudinal section. F ig. 3 is an enlargec detail view.

My improved grease cup includes, as shown in the drawings, a barrel l. having an apertured base 2 adapted to be secured into the casing or support of the part to be lubricated, the other end of the barrel terminating in a hollow stem or sleeve which has a series of hexagonal portions 3, t and 5, the portion 4l being arranged eccentrically to the portions and 5. rlhe'base 2 is detach ably connected with the barrel, the locking means being shown in the form of lateral outwardly projecting` spaced apart lugs 6 on the barrel adapted to engage with inwardly extending spaced apart Hangers on the base, each of these flanges having a stop 8 which limits the turning movement between the barrel and base. A plunger 9 is iitted grease-tight within the barrel l and this plunger has a rod 10 which fits within the sleeve ot the barrel. A coiled spring l2 hugging the inner wall ot the barrel is positioned between the plunger and the base end of the barrel, and this spring normally maintains the plunger at the sleeve end of the barrel. The latter has an inwardly eX- tending flange 13 which forms a seat for the spring at its base end.

A tool complementary to the grease cup has an elongated handle 2O and a tube 21 which is provided with a bore of hexagonal form, indicated at 22, at one end, the

bore of the tube at the other end being preferably circular in form, as at 23. Equally spaced around the sides of the tube are three spring arms 2st. Each ot' these arms is iXedly secured to the tube at one end, its other end having a lug 25 which projects into the tube through an aperture provided for that purpose at a point slightly to one side of the center line of the hexagonal surface through which it extends. A rod 26 paralleling the handle throughout its greater portion extends a slight distance into the tube Vthrough the bore 23, a spring 27 coiled about the rod and seated between the tube and stop 28 on the rod normally maintaining the rod in its outermost position. A lever 30 has a pivotal connection with the rod at its outermost end and is fulcrumed on the handle in such position that its free end and the end ot the handle afford a hand grip tor the manipulation of the rod.

The tube is placed over the hollow stem or sleeve of the grease cup and is `iorced thereonto. Engagement between the sleeve and the lugs 25 forcing the spring arms outwardly,l such arms returning to their normal position when the tube has been forced sufiiciently far on to the sleeve to allow the lugs to engage with the surfaces of the portion 4 ot such sleeve, the tool being thus locked with the grease cup. The projection of the lugs through the tube at one side ot` the center line oi the hexagonal surface insures a snapping of the lug into engagement with the fiat surface of portion 4 immediately adjacent the lug. This insures the positioning of the lug so that an outward pull on the tool will cause the lug to engage the portion 5 at a point where two of its surfaces merge, this angular point thus forming a stop for the lug. In removing the tool it is necessary to give it a slight turn so as to expand the spring arms to bring the lugs into a plane with the surfaces of the portion 5. The extreme end of' the tube engages the stem portion 3 and serves asa `wrench for turning the barrel relatively to its base so as to detach these parts. VhenV detached the barrel is securely held by the tool. Pressure on the lever 30 will force the rod 26 farther into the tube and bring it in contact with the plunger 4rod 10, continued pressure serving to force the plunger against the tension of its spring toward the base end of the barrel. With feeding.

the plunger forced inwardly the barrel may be placed in a can of grease, release of the lever causing the plunger to quickly re-V.

turn to its normal position under the pres sure of its spring, thus sucking the grease into the barrel. With the latter so filled itis attached to its base, and the lever 30 againimanipulated to force the tool rod 26 Vand the plunger rod lOagainst the tension of the respective springs l2rand 27, this movement forcing the grease in the barrel through the passageway kof its base to the machine part to be lubricated.` 1When' a sui'iicient amount oi lubricant hasvthus heen forced home, the barrel may be again filled and the tool immediately detached, leaving the grease cupV filled ilor a later forcible l claim as my invention:

l. ln combination, a'grease cup having an apertured detachablebase, a spring held plunger, said grease cup having an opening `at one end permittingaccessto said,l plunger, and a plunger actuating element detachably connected With said grease cup.

2. ln combination, a grease cup having an apertured detachable base at one end' and a sleeve at its opposite end, a spring held plungerV Within said cup and having a portion extending into said sleeve, and a plunger actuating element adapted to be detachably connected with said grease cup, said plunger actuating element including a spring controlled rod adapted to be rojectedV into said sleeve to actuate said p un` ger.

3. ln combination, a grease cup having Lan apertured detachable base at one end and a sleeve at its opposite end, a spring held plunger Within said cup having a portion extending into said sleeve, a tubular memberadapted to be detacliably connected with said sleeve, a spring controlled rod leX- tending into said tubular member, and

means for projecting said rod into said sleeve to actuate said plunger.

ln combination, a grease cup having an apertured detachable base at one end and a sleeve at its opposite end, a spring held plunger Within said cnphaving a por-Y tion extending into said sleeve, a tubular member adapted to detachably connected With said sleeve, a handle en said member, Va spring eontio led rod extending into said tubular member, and a lever secured to said rod and iulcrumedon said handle for projecting said rod into said sleeve to actuateY said plunger.

ln combination, a grease cup having an apertured,detachable hase at one ond ain; a sleeve at its opposite end, the outer surface of said sleeve having plurality oi Vdat faces, a sprin held plunger Within said cup and having a portion extending intosaid sleeve, a tubular member adapted to Lit bore said sleeve and having a portion ot its ejiied to e the flat faces of said means Viti detacliably securing said extending into s' tubular il fil said into said sleeve, atnbular to tending into tubular member, and means" ier proiecting said rod into said to act-nate said plunger. p

ln testimony whereof lhave signed this ycilica tion.
